Customers and employees of an Oakland clothing store were evacuated Monday night after a man attempted to rob the store, authorities said.

The attempted robbery occurred at 8:38 p.m. at the K&G Fashion Superstore, at 3020 E. Ninth St., said Officer Johnna Watson, a spokeswoman for the Oakland Police Department.

Officers reportedly responded after a 911 caller said a robbery was in progress inside the clothing store. Within two minutes, police arrived on scene and employees and customers were evacuated.

Investigators determined that an unknown male suspect entered the business and demanded cash from an employee, Watson said. He reportedly fled the business before police arrived without any cash in hand.

Authorities are scouring video surveillance from the store to identify the suspect.

Anyone with information can contact the Oakland Police Department at (510) 238-3326.
